---------------------------------
Summary: Failure in RS when using large size bucketcache
Key: HBASE-10643
URL: https://issues.apache.org/jira/browse/HBASE-10643
Project: HBase
Issue Type: Bug
Components: regionserver
Reporter: Biju Nair
When RS is brought up with XX:MaxDirectMemorySize of 22GB or higher, RS fails
after a successful start. From the RS logs it looks like the bucketCache memory
allocation is taking more time makes the RS considered dead by ZK. One option
to fix the problem would be to allocate the bucketCache before registering with
ZK.
